The fuel cell-electric drive system is an attractive technology for a sustainable mobility with zero emissions. Hybrid fuel cell battery powertrain configurations in particular are gaining more and more attention thanks to the advantages they offer in terms of fuel cell downsizing. Such a solution usually implies the presence of several DC/DC converters to be able to perform the power sharing between fuel cell and battery pack. In this work, a fuel cell battery passive hybrid powertrain is proposed. This configuration eliminates the need for costly DC/DC converters. The power sharing is regulated directly coupling the voltages of the fuel cell and of the battery pack.

Abstract
The fuel cell-electric drive system is an attractive technology for a sustainable mobility with zero emissions. Hybrid fuel cell battery powertrain configurations in particular are gaining more and more attention thanks to the advantages they offer in terms of fuel cell downsizing. Such a solution usually implies the presence of several DC/DC converters to be able to perform the power sharing between fuel cell and battery pack. In this work, a fuel cell battery passive hybrid powertrain is proposed. This configuration eliminates the need for costly DC/DC converters. The power sharing is regulated directly coupling the voltages of the fuel cell and of the battery pack.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
